Sorenson resigned from the state Senate in October, after a special state investigator found that he had violated legislative ethics rules when he took money from campaign committees connected to Rep. Michele Bachmann’s (R-MN) failed 2012 presidential bid. Sorenson served as Bachmann’s Iowa state campaign chairman before bolting to support former Rep. Ron Paul’s (R-TX) presidential campaign.

Sorenson lawyer, Theodore Sporer, told the Register on Wednesday that FBI agents on Nov. 20 took computers and other materials from his client’s home.

“We were not notified that he was the target of any investigation,” Sporer told the Register. “They took computers and things that would be used to verify or validate communications with presidential entities.”

Agents were at Sorenson’s home for several hours, and took computers belonging to his children.

“I assume it’s just kind of a dragnet to sweep for anything they could possibly find,” Sporer said. “They’re very thorough.”
